Thickness Φ 42 It was used to drill a hole of Φ 27 in a 3 mm thick stainless steel pipe. Result The tooth became dreadful with just the third hole. I care about the number of revolutions and loads pretty much, but I can not do it at all. It takes quite a while to drill. When drilling with Nicotech's "bimetallic hole saw" under exactly the same use condition, it became useless after about 50 places. I always use Nicotech, but this time I tried buying it because I have a lot of drilling. I was expecting a little because it costs about twice, but sorry. Again it is limited to bimetallic hole saws.

The carbide blade was said to be prone to chipping, although I purchased additional Horse of Speed ​​as a spare, I could successfully process 8 phi 90 holes (thickness 2.4 mm) without blundering.If you purchased Hyth's Holosaw did not use, processing time was short, although it was good, although it was good, the reserve Holsau nearly doubled the price, I was surprised.

Although it is cheap, it purchases quite a lot, but I will never last long, I think that it is suitable only for small lot processing, if SS material etc. is good, SUS may be a little impossible, if there is a losing around If you use a bad worker, the blade will fly soon. There are too many eyes, too many? Do not worry about opening a round pipe etc.

Because the price is cheap, I often purchase it, but I think that the out-of-order is great. If you hit it, it will last a long time, if it goes out several times, the tip is detached or missing at the worst first time · · ·. I think that it is not a harsh condition, but as a professional manufacturer of metal cutting theory and carbide chip · · · in item description, the tip used by a specialized manufacturer of carbide chip is made by Sandvik. I think that I did not say this before, but I wonder if I can trust or not ... / /.

Drilling of stainless steel plate (thin plate)

There is no dissatisfaction with sharpness. As for durability, I can not say anything because the number of times of use is still small. Although it may be a suitable product even if considered in terms of price, it is a product of its own because it is made in Korea. Is it a product that will be in time for hurried less machining?

It was a commodity with no durability as in other people's evaluation. We made a hole in the thin plate (while wearing low rotation and cutting oil as noted), but all the chips were damaged at the time of the third hole drilling. Is it a defective product? I think that you should buy other items even if you double the price.

It was φ18 that I used, but I thought that it was better to have three blades and a hole saw of Monotaro as 4 blades and still last longer. In a bad time all the chips flew without being able to open one hole.

Even cheap things may be used to drill the bulb socket, but since this was only 37 mm, it seems to last long without the blurring that I used, but with about 400 rpm I have difficulty in choosing an inexpensive electric drill with torque Did. With this, it was possible to remodel it from a special light bulb to a fluorescent lamp of 100 yen uniform.
